After removing multiple layers of wallpaper, I use sheetrock joint compound and fill the nail holes with a 2-3 inch putty knife (bigger gaps-holes take multiple layers) after it dries I 'sand' it flush with a wet sponge. Then I roll the walls with flat white paint to seal the grit. Then I skim the walls with a 12-14" knife/blade with joint compound and repeat the sponge 'sanding'. Time consuming, but when it's done it looks great.
